BEYOND WC25-2D-SD19.5-WC03
Industrial 19.5mm 2D Indexable U-Drill | High-Performance CNC Boring Body
High-Efficiency 19.5mm Indexable Fast Hole Drilling
The BEYOND WC25-2D-SD19.5-WC03 is a professional indexable insert drill engineered for rapid material removal in CNC machining centers. As a specialized fast hole U-drill, it features a 19.5mm cutting diameter with a 2D depth ratio and a 25mm straight shank. This tool is optimized for internal cooling drilling in carbon steel, alloy steel, and stainless steel, ensuring maximum productivity for large diameter metal boring projects.
Model Code Specification Breakdown
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|

| Shank Diameter | 25.0 mm | 0.984" |
| Max Drilling Depth (2D) | 39.0 mm | ~1.535" |
| Product Model | WC25-2D-SD19.5 | WC0.98-2D-SD0.77 |
Material Excellence & Advanced Flute Design
Premium Body Material: This 19.5mm U-drill is crafted from high-strength 20CrMnTi alloy steel, subjected to vacuum quenching for superior surface hardness and anti-vibration performance. This ensures the indexable drill body remains stable under the high temperatures of high-speed drilling.
Optimized Spiral Flute (U-Slot): Features an enlarged spiral flute designed for rapid chip evacuation. The precision U-groove geometry works in tandem with dual internal cooling holes to flush chips out instantly, preventing heat buildup and tool deflection in shallow hole drilling.
Recommended Cutting Parameters
Baseline recommendations for the 19.5mm U-drill (Adjust based on material):
- Cutting Speed (Vc): 110 - 190 m/min.
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 19.5}$$
- Coolant Strategy: Internal cooling is mandatory for effective chip flushing and tool cooling.
WC Type U-Drill: Advantages & Considerations
- Uses WC series trigon inserts with 3 cutting edges (Economical).
- Stable entry even on uneven or inclined workpiece surfaces.
- Lower cutting resistance compared to square insert drills.
- Roughing tool; hole tolerance is typically (+0.1/-0.2mm).
- Requires consistent high-pressure internal coolant supply.
Verified Global Feedback
"Solid Rigid Body"

Expert Q&A
Q: Does this include the Torx wrench and screws?
A: Yes, each BEYOND drill body includes the necessary high-strength screws and the correct Torx wrench.
Q: Can I use this for blind holes?
A: Yes. The WC U-drill provides a relatively flat bottom, perfect for blind hole boring in CNC operations.
Q: Is internal cooling mandatory?
A: Yes. To ensure the 19.5mm diameter clears chips effectively and prevents overheating, internal coolant is essential.
Quick Tip: 2D-5D CNC Drill Selection
Choosing the right depth is crucial. 2D drills (like this SD19.5 model) offer maximum rigidity and are best for high-feed roughing. 3D to 5D drills allow for deeper holes but require significantly higher coolant pressure and reduced feed rates to avoid tool deflection.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
